Automatic effects tails flushing during bounce

Many VST plug-ins do not properly flush their effects tails via reset state transitions. In some cases, exporting multiple clips or arrangements could result in tails unexpectedly appearing in the export/bounce.

To address this, Cakewalk now automatically flushes effects tails during export/bounce operations to prevent left over effects tails from leaking into exports or being heard.

By default, tails are flushed until a threshold of -70dB is reached or 20 seconds of silence is detected, whichever occurs first. The dB threshold and max duration can be specified via the following Aud.ini variables that can be set in Edit > Preferences > Audio - Configuration File:

BounceFlushTailsMaxDurationSec=n (0 to 60; default is 20; set to 0 to disable tails flushing) Effects tails maximum flush length while bouncing (seconds).

BounceFlushTailsThresholdDb=n (-120 to -40; default is -70) Effects tails flush gain threshold while bouncing (dB).

On export, the audio engine will first hard flush any effects tails from all active plug-ins referenced in the project, including track/bus effects, clip effects, effects chains, ProChannel as well as instruments. Flushing tails is done both pre and post bounce/export in order to prevent unwanted tails from sounding after a bounce or appearing in exports after playing a project.

Effects tails flushing is done in efficiently using parallel processing when the multi processing engine is enabled and is normally very fast. Flushing progress is shown on the toolbar during the bounce. If you wish to disable this, set BounceFlushTailsMaxDurationSec to zero.
